8 Claims. (Cl. ,2P-234) This invention relates to 'y construction for trousers and particularly to a fly closed by a slide fastener of the zipper type.

One of the objects of the invention is to provide Y5 affly construction in which, notwithstanding the employment of the zipper slide fastener, the right fly as well as the left is made of one integral piece of conventional shape instead of requiring the use of an additional piece of cloth at the 10 bottom of the right fly.

Another object of the invention is the provision .of a yconstruction comprising theright and vleft cooperating flies, curved at their lower ends in conventional manner, with one strip of the zipper slide fastener extending along that edge "of the right fly which will be stitched to the right front of the trousers down to a point adjacent the beginning of the lateral curvature of the fiy, and then being diverted from its rectilinear course a'nd extended across the fly to the opposite edge,

and the left fly having on its inner side the coop-l erating zipper strip extending 'lengthwise of the'fiy intermediate its longitudinal edges, and curving to correspond tothe curvature of the complernentary zipper strip.

Other objects of the invention relate to several novel arrangements for finishing the raw lower ends of the cooperating zipper strips. y In the drawings which accompany and form a part of the following specification and throughout the several figures of which the same characters of reference have been employed to designate identical parts:

-Figures 1 and2 are respectively, viewsin side '35 elevation of the confronting-faces of the right and left nies with the zipper strips in position;

Figure 11 is a similar view from the outside of 60 the trousers, a layer of the fabric being broken away to reveal the pad.

Before adverting to a detailed description of the present invention, it may b'e stated in distinguishing the new from what is old, vthat the flies are narrow fabric strips having parallel edges extending for more than half the length of the fly, the edges then curving in the same direction, one being concave and the other being convex so that the fly has a lateral curved and substantially pointed extension to one side. It is customary where a slide fastener of the zipper type is 4ernployed to make theedge of the y remote from the free edge straight throughout its length and to attach one of the zipper strips to this straight edge by stitching. The zipper strip is customarily formed of a series of hooks attached to one piece of braid by way of finish to another lpiece of braid, the longitudinal edge of the zipper strip opposite the hooks being open between i f the two pieces of braid. It is customary in the art to insert a roughly triangular piece of fabric. additional to the flies, between the pieces of braid constituting the zipper" strip, and to stitch it in place. This necessitates not only the employ- 85. ment of additional material, but lalso an added step in the construction of the ily. involving anadded item of expense, and besides it makes an inferior crotch finish.

It was with the object of improving the cony struction of the fly as well as lessening the cost of making the same that the principalv .feature of the present invention was evolved which avoids using an additional piece of material.

Referring -now in detail tothe several figures and first adverting to the group of Figures 1 to 5, inclusive, the numerals 1 and 2 represent respectively, the right and left flies. On the outer faceof the right fiy a zipper `strip 3 is arranged with its fabric edge adjacent the edge of the fly I which will be stitched to the right side of the trousers and continuing down to the point 4 which in the embodiment of the invention shown is somewhat more than half way down the edge kof the fly, from which point the zipper strip is'de- `105 flected away from the edge with which it has substantially coincided and extends inclinedly across the fly to the yopposite edge. That portion of the zipper strip which parallels the edge of the ily is stitched to the fiy by a single row of stitching 11.0

5 while the portion of'said "zipper strip which extends across the y is stitched thereto by double rows of stitching 6 and 7. The lower edge 8 of this zipper strip is finished in any of the three modes presently to be described and the upper edge of the zipper" strip may be sewed into the belt line in the manner indicated at 9 in Figure 10 and which is well known in the tailoring art.

The complementary zipper strip 10 extends longitudinallyof the intermediate portion of the left ily 2 preferably parallel to the edges of said fly, and below the middle of the 'y itis made to veer toward the convex edge of the ily with a curvature'corresponding to that of the zipper strip 3, the relation of the zipper strips being illustrated in the assembled ily shown in Figure 4.

It will be observed that a buier strip 11 of any suitable material crosses the linear junction of the slide fastener adjacent the lower ends of the series of hooks 12, andthat just below the said buffer strip, the zipper strips are positively locked together -by a staple 13. The buffer strip is for the purpose of engaging the slide 14 at the lower limit of its travel bringing it yieldingly to a stop and preventing its direct engagement with the staple 13 which might be torn from the fabric by violent operation of the slide.

Below the staple 13 the hooks are absent from the zipper` strips leaving the fabric ends 15 and 16 which may be nished in any of severalways, one of which is illustrated in Figure 8, showing that the end 16 of the zi per" strip 10 is cut flush with the convexedge the left y and surged together with `the ily edge 17. Il'he lower end 15 of the zipper strip 3 terminates short of the convex edge of the right fly 1 being stitched to the face of said fly with its free edge 18 turned under.

In Figure 6 another form is illustrated of nishing the lower ends of the flies. The lower end Wner as the lower end 16 of the 16 of the. zipper strip 10 is surged to the convex edge of the left ily 2, in the same manner` 'as in Figure 8. The lower end 15 of the zipper strip 3 is stitched to the face of the ily 1, being folded about the convex edge of said y and stitched beneath the lining 19 of said fly as best illustrated in Figure 7.

Still another mode of nishing the ends ofthe flies is illustrated in Figure 9 in which the end 16 of the zipper strip 10 terminates beneath the surging at the convex edge of the left y 2 while the lower end 15 of the zipper strip 3 is stitched against the fly 2 and has its free edge surged to the convex edge of the ily 2 in the same manzipper strip 10. zlpper" strips are concealed between plies of the waist band of the trousers inthe manner known to the art and which forms no part of the present invention. However, it has been discovered that in pressing garments having flies provided with the zipper type closure, protection is needed to keep the slide from pushing a hole through the lfront of the trousers by the pressing action. To avoid this a small patch of fabric 201s sewn on the opposite face of the left fly to that upon which the zipper strip 10 is secured, said patch being posi. tioned to come between the slide and the left front of the trousers when the zipper slide is in closed position, its function being to pad the slide and prevent it working through the front of the trousers when under pressure. y

While I have in the above description defined 'I'he upper ends of the 'l what I believe to be preferred and practical forms in lapped relation,

of the invention, it will be understood to those skilled in the art that the specific details of construction as shown and described are merely by way of example excepting as they illustrate the subject matter of the claims and are not to be construed as limiting the scope of the invention.
